Rotary dryer with multiple stages of raising plates

Abstract

The invention relates to a rotary dryer with multiple stages of raising plates. The rotary dryer comprises a cylinder, a vertical raising plate, a vertical arc raising plate and an inclined arc raising plate; the vertical raising plate, the vertical arc raising plate and the inclined arc raising plate all comprise working plates and baseplates connected with each other; the baseplates are mountedon the inner wall of the cylinder; the working plate of the vertical raising plate is perpendicular to the baseplate; the working plate of the vertical arc raising plate is perpendicular to the baseplate, and the top end is arched; the working plate of the inclined arc raising plate forms an acute angle with the baseplate, and the top end is arched; the working plates of the vertical raising plate, the vertical arc raising plate and the inclined arc raising plate have the same widths and increasing heights; and the vertical raising plate, the vertical arc raising plate and the inclined arc raising plate are uniformly distributed in a feed area, a middle area and a discharge area of the cylinder respectively, and are in the same directions. The rotary dryer adopts arrangement of the multiple stages of raising plates, and the heights of the raising plates are gradually increased, so that the drying effect is guaranteed, and the better heat value utilization rate is achieved.

Description

technical field [0001] The invention relates to a rotary dryer, in particular to a rotary dryer with multi-stage lifting plates. Background technique [0002] The rotary dryer consists of a horizontal cylinder and a lifting plate installed on the inner wall of the cylinder. When working, the material and hot air enter the cylinder together, and the driving mechanism drives the cylinder to rotate. The material turns up and down with the lifting plate. It is dried after being fully exposed to hot air. [0003] The existing rotary dryer either takes a long time to dry the material but the scattered area is small and unevenly distributed, there are thermal voids and the utilization rate of the calorific value is low, or the material scattered area is large and evenly distributed but the drying time is short and the drying effect is low. not good. Therefore, there is an urgent need for a rotary dryer so that it can achieve better heat value utilization and drying effect. Cont...
